The ISO 27001 standard is an international standard that deals with information security management and serves as a model for the establishment, implementation, operation, monitoring, review, maintenance and improvement of an information security management system.
The standard touches on all aspects of information security in the organization while understanding the risk and building a defined policy at the IT level – computing and communication, physical security, records security – physical substrates that carry information, employee reliability and security among business interfaces.
In order to implement the standard, the organization will have to adopt structured methodologies of information security management and information security risk management, where the goal is to protect all types of information within its scope against all identifiable potential threats. The standard is international and recognized all over the world.

What is ISO 27001 standard?
The ISO 27001 standard is an abbreviated designation of ISO/IEC 27001. This is an international standard whose main purpose is the management of everything related to information security in organizations. In 2005 this standard was published for the first time by the International Electrotechnical Commission and the International Organization for Standardization (ISO), and after seven years in 2013 it was upgraded to the same standard that we know. A European update of the ISO 27001 standard was published in 2017.
What is the purpose of ISO 27001 standard?
The goal of this standard is to help each and every organization make the information in its possession more secure. Something that can be done by implementing everything related to the requirements specified in the standard: building a mechanism whose purpose is to identify risks in the organization’s information security, writing all the procedures required in order to be sure that all the information data in the organization is indeed safe and available for quick retrieval at any given moment, backing up all this data, and regular maintenance and updates of the information security management system of that organization. As of 2021, any organization that meets all the requirements of the ISO 27001 international standard can benefit from the organization’s certification after a successful audit by the certification body.
Why is ISO 27001 Important?
ISO 27001 is crucial for organizations aiming to safeguard their information assets, comply with regulations, and build trust with clients. It provides a structured framework for managing and securing sensitive data, mitigating risks associated with cyber threats, and demonstrating a commitment to information security. Industries such as finance, healthcare, and IT services particularly benefit from ISO 27001 due to their need to handle large volumes of sensitive data securely. For instance, financial institutions use ISO 27001 to protect customer information and comply with stringent regulatory requirements, while IT service providers leverage it to reassure clients about their robust security practices. It provides a structured framework for managing and securing sensitive data, mitigating risks associated with cyber threats, and demonstrating a commitment to information security. With increasing incidents of data breaches and stringent legal requirements, ISO 27001 ensures organizations stay resilient and competitive.
What Are Three Principles of ISO 27001?
The foundation of ISO 27001 lies in three core principles:
1. Confidentiality:
- Ensuring that information is accessible only to those authorized to view it.
- For example, implementing role-based access controls ensures that sensitive financial data can only be accessed by accounting staff, reducing the risk of accidental disclosure.
2. Integrity
- Maintaining the accuracy and completeness of information.
- A common policy is using version control systems for documents, ensuring any changes are tracked, and unauthorized modifications are flagged.
3. Availability
- Ensuring that information and systems are accessible when required.
- Organizations often adopt redundant server setups or cloud backups to minimize downtime and ensure critical systems remain operational during unexpected disruptions.
Protection of the organization’s information assets and more
Applying and implementing the ISO 27001 standard will ensure your organization maximum protection of its information assets. The purpose of this standard is for organizations to establish systems whose main focus is information security management. That is, a system, through which it will be possible to manage and improve everything related to the security system that should prevent criminal acts of stealing information from the organization’s information asset system. The implementation and assimilation of the ISO 27001 standard will guarantee the organization that access to the organization’s information will only be in the hands of authorized people that the company has defined in advance. The management of the information security system will ensure the preservation of the information found in the organization in its current format and immediate access to the organization’s databases at any given moment.
The benefits of implementing and assimilating the ISO 27001 standard are many, the main of which are reflected in the organization’s risk management plan, that is, control over all those security risks that can occur in the present and in the future. Reduction of the organization’s expenses, optimization in everything related to the organization’s processes and of course a marketing advantage over other competing companies.
Is ISO 27001 standard also intended for your organization?
A standard for information security management, that is, the ISO 27001 standard is intended for any organization that wishes to protect itself against loss of information, information leakage and other risks related to the organization’s databases. Organizations that must comply with this standard, that is, an obligation and not a permission, are those that sell computerized services to the government, organizations that provide computer systems that are linked or embedded in government offices, and organizations and companies that transmit computerized information. Implementation of this standard in your organization will allow you to benefit not only from the same organized information security management, but also from one-on-one control over the flow of existing information in the organization. As of today, there are many companies that publish tenders that require this standard as a threshold condition for participating in this or that tender.
How Does ISO 27001 Work?
ISO 27001 provides a systematic approach to managing information security through the implementation of an Information Security Management System (ISMS). Here’s how it works:
1. Risk Assessment
- Identifying and evaluating potential threats to information assets.
- Prioritizing risks based on their likelihood and impact.
2. Risk Treatment
- Implementing controls to mitigate or eliminate identified risks.
- Accepting residual risks where necessary.
3. Continuous Monitoring
- Regularly reviewing and updating the ISMS to adapt to evolving threats and business needs.
- Conducting internal audits to ensure compliance with the standard.
4. Certification
- Undergoing an external audit by an accredited certification body to validate compliance with ISO 27001 requirements.
- For example, a mid-sized software company implemented ISO 27001 to address growing client concerns about data security. By establishing clear policies, conducting thorough risk assessments, and providing employee training, the company reduced security incidents by 40% within a year. Additionally, the certification played a pivotal role in securing a major contract with an international client, emphasizing the tangible benefits of a well-executed ISMS.
What will enable the implementation and implementation of ISO 27001 standard for the organization?
- More extensive work options – turning to international markets, working with government offices and working with the largest companies in the economy
- Competing in public tenders – information security for businesses at the highest standards is an advantage.
- Streamlining of the organization – the standard enables smart streamlining of the organization in everything related to work processes and maintaining its databases.
Implementing and implementing the ISO 27001 standard or in other words implementing an information security management system will reduce your organization’s exposure to cyber attacks and various security breaches. As of today, you have the option of receiving a certificate of certification if you implement everything related to this standard, which will indicate that your organization is indeed a reliable and high-quality organization. In addition, anyone interested in using your organization’s services will be aware that even in the unlikely event that the business collapses, all of your organization’s information is protected and backed up, so the business will be able to recover quickly and its customers will of course be able to enjoy high-quality and fast service, as expected.
Implementation of ISO 27001 standard – independently or through experts?
Since in order to implement and assimilate the standard the organization will have to understand what is required of it within the framework of the standard, learn everything related to information security management, risks related to information security and various concepts from this world, most organizations prefer to use the services of experts in the field of information security management who are experienced in everything related to implementation and the implementation of the ISO 27001 standard, such as the experts of the CyberSafe company. The Cybersafe company, which has extensive experience in the implementation and assimilation of everything related to the ISO 27001 international standard, will be happy to perform the required work for your organization, and accompany you on the way to the standard.
Another important thing that must be taken into account is that even large companies that wish to appoint someone from the company and implement the things themselves must understand that organizations with a large scope of activity must use the services of an expert in the field of information security in order to benefit from professionalism and the correct perspective of things. Carrying out things from within the organization is sometimes a quite unprofessional plan, since an employee of the company cannot necessarily check himself in all the subtleties. Therefore, most companies prefer to hire outsourcing services in everything related to information security when the main goal is supervision and control of all processes from the outside.
